I think I shall be able to do at least 12mpg in city and 17 highway. My engine harness is falling apart that makes me think that some sensor shorts out thus giving me very rich mixture. Any ideas where to get harness for decent price? Friend of mine has 20% discount with MB dealer and he can get harness for me for $420. Does it sound fare?
